[0029] like Figure 2 As shown, an electromagnetic pulse protection device comprises an electromagnetic pulse monitoring module, an electromagnetic pulse protection device, an electromagnetic pulse communication module and a monitoring module; the electromagnetic pulse monitoring module is connected to the electromagnetic pulse protection device; the electromagnetic pulse monitoring module, the electromagnetic pulse protection device and the electromagnetic pulse communication module are respectively connected to the monitoring module; The electromagnetic pulse monitoring module detects the electromagnetic pulse energy impact in the circuit. When the electromagnetic pulse energy reaches the preset minimum voltage or minimum current value of the electromagnetic pulse protection device, the electromagnetic pulse protection device is activated to clamp the voltage or current to less than the preset value; the electromagnetic pulse communication module is used to feed back the electromagnetic pulse protection device protection data and the health of the electromagnetic pulse protection device collected by the monitoring module, and output a real-time monitoring signal and a detection result signal; The electromagnetic pulse monitoring module includes an RC trigger device module and a signal sampling module; The RC trigger device module is used to start the electromagnetic pulse protection device and introduce the electromagnetic pulse when the electromagnetic pulse wave energy impact value in the circuit reaches a preset threshold; the signal sampling module is used to judge and convert the pulse energy.

[0030] The electromagnetic pulse monitoring module also includes a controllable discharge gap with an arc extinguishing circuit, and the controllable discharge gap is used to control the electromagnetic pulse protection device to work when the applied voltage value or current value exceeds the starting voltage value.

[0031] The electromagnetic pulse protection device includes a pressure-sensitive component and a FS high-pass filter module; the pressure-sensitive component includes a dual-energy wave sensitive ceramic element and a controllable capacitance filter; The dual energy wave sensitive ceramic element can withstand 10 / 350㎲+8 / 20㎲ combined wave impact, 20 / 500ns PCUI dual exponential wave 500A impact capability, and the combined wave limiting voltage is less than 700V; The controllable capacitance design filter has a reliable thermal trip device and adopts a varistor-gap series structure; the FS high-pass filter module is used for device startup to divert pulse energy.

[0032] The electromagnetic pulse communication module includes an equipment on-site counting and display module and an equipment remote communication module; the equipment on-site counting and display module is used to display the real-time monitoring data of the electromagnetic pulse monitoring module on the device panel; the remote communication module transmits the real-time monitoring data of the monitoring module and the prevention and control instructions given by the background center in real time through the device communication interface.

[0033] The specific electromagnetic pulse protection method of the present invention comprises the following steps: Step 1: Health monitoring and replacement The electromagnetic pulse protection monitoring module first obtains the health of the electromagnetic pulse protection device. This health is calculated based on the working time and fatigue coefficient of the electromagnetic pulse protection device, where the fatigue coefficient is defined as the ratio of the duration of electromagnetic pulse exposure to the total working time during the working time of the electromagnetic pulse protection device. If the health is lower than the set health threshold, it means that the electromagnetic pulse protection device has approached or reached its service life limit, and the protection effect may be greatly reduced. At this time, the electromagnetic pulse protection device needs to be replaced to ensure the effectiveness of the protection. Otherwise, proceed to the next step.

[0034] Step 2: EMP Protection Assessment The electromagnetic pulse assessment module generates an electromagnetic pulse protection assessment container based on the electromagnetic pulse energy limit of the target protection equipment and the health of the electromagnetic pulse protection device. The container is connected to the electromagnetic pulse protection monitoring module to receive and process the data from the monitoring module. By comparing the relationship between the current intensity of the electromagnetic pulse and the degree of interference of the target protection equipment, and the difference between this relationship and the benchmark relationship (i.e. the corresponding relationship between the initial intensity of the electromagnetic pulse and the degree of interference of the target protection equipment), the protection deviation of the electromagnetic pulse protection device is calculated. This deviation reflects the gap between the actual use of the protection equipment and the ideal protection state.

[0035] Step 3: Guard Deviation Calibration The relationship between the electromagnetic pulse intensity and the interference degree of the target protection device obtained in step 2 is sent to the protection deviation calibration module. This module calibrates the protection device according to the protection deviation of the electromagnetic pulse protection device to eliminate or reduce the deviation. The calibrated electromagnetic pulse protection intensity is obtained by adjusting the protection device parameters or strategies under the same interference level, aiming to more accurately match the actual needs of the target protection device. The calibration results are then sent to the electromagnetic pulse protection device to guide subsequent protection control.

[0036] Step 4: Real-time interference monitoring The data acquisition device collects the interference degree data of the target protection equipment in real time and compares it with the preset target interference degree. If the real-time interference degree is not greater than the target interference degree, it means that the current protection strategy is effective and no further adjustment is required. Go directly to step 7 to complete the protection equipment control. Otherwise, according to the difference between the target interference degree and the real-time interference degree, go to the next step to dynamically adjust the protection strength.

[0037] Step 5: Dynamically adjust protection strength According to the interference difference obtained in step 4, the electromagnetic pulse energy to be suppressed is calculated, and then the required protection strength of the electromagnetic pulse protection device is determined. Based on this calculation result, the electromagnetic pulse protection device control module adjusts the protection equipment to the required protection strength until the real-time interference level is reduced to below the target interference level, and then enters the next step for further fine adjustment.

[0038] Step 6: Correct the protection strength In order to further improve the accuracy of protection, the present invention also considers the change in the degree of interference per unit time (i.e., the change in the degree of interference per unit time), and infers the change in the electromagnetic pulse energy per unit time through this change. Based on this change, the corrected protection strength of the electromagnetic pulse protection device is calculated, and the protection strength of the protection equipment is adjusted accordingly. This step ensures that the protection strategy can be dynamically adjusted with the changes in the electromagnetic environment to maintain the best protection effect.

[0039] Step 7: Complete the EMP protection device control After the calibration, adjustment and correction of the above steps, the electromagnetic pulse protection device has reached the best protection state according to the current electromagnetic environment and the actual needs of the target protection equipment. At this point, the control process of the electromagnetic pulse protection device is completed to ensure that the equipment can operate stably in a complex electromagnetic environment.
